  abstract = "This paper proposes an extension to the televisionwatching
              paradigm that permits an end-user to enrich
              broadcast content. Examples of this enriched content
              are: virtual edits that allow the order of presentation
              within the content to be changed or that allow the content
              to be subsetted; conditional text, graphic or video
              objects that can be placed to appear within content and
              triggered by viewer interaction; additional navigation
              links that can be added to structure how other users
              view the base content object. The enriched content can
              be viewed directly within the context of the TV viewing
              experience. It may also be shared with other users
              within a distributed peer group. Our architecture is
              based on a model that allows the original content to remain
              unaltered, and which respects DRM restrictions
              on content reuse. The fundamental approach we use
              is to define an intermediate content enhancement layer
              that is based on the W3C’s SMIL language. Using a
              pen-based enhancement interface, end-users can manipulate
              content that is saved in a home PDR setting.
              This paper describes our architecture and it provides
              several examples of how our system handles content
              enhancement. We also describe a reference implementation
              for creating and viewing enhancements."
